My question is this:
When you have your automatic air/heat working and you set the temperature to say, 76, is it that:
The system should blow out whatever temperature air it needs to to bring the temperature in the vehicle down or up to 76.
OR
The system should blow out air from the vents that is exactly 76 degrees therefore eventually bringing the temperature in the cabin to 76.
Which should it be?
If it matters I have a 2004 Chevy Tahoe.
It will blow heat/cold out to get to the desired temperature, then reduce the fan. It won't spit out the exact air temp, but will get closer to it as the temp in the cabin gets to the desired temp. There is a blend door which can vary the heat/cold as needed to maintain the temp. This is how my '06 Silverado with auto temp control works. Other vehicle brands may work differently.
